Hi Scotty,
I have a 2016 Toyota 4Runner with 86k miles. I live in Massachusetts, in the heart of the salt belt. I took it to a shop to get an undercoating done. While they did a thorough job, they were a little overzealous - they undercoated the exhaust system in addition to the entire underside of my vehicle. I've been noticing a burning smell when driving it since then, almost like asphalt being poured. I've been told the undercoating on the exhaust will "burn off" after a time. I haven't seen any flames, but the smell makes me nervous. Am I in trouble?
Thanks for your time and great YouTube videos,
Robert
It will burn off in a few days. Nothing to worry over.
Well, it seems they cannot do the job right or they don't care. Never use rustproofing material on exhaust and brakes. At least where I live, it is written in instructions.
Seems a bit sloppy to me. I would have masked it off. It doesn't take that long.
You're not in trouble, but you will have an annoying smell for a while.
A mechanic at Mineke once told me 'it is pointless to undercoat the exhaust'. Usually you would replace the exhaust after it rusts too bad.
